JPG to PNG Converter
100% in your browser — nothing is uploadedMost often needed because an upload form, design tool, or print workflow demands PNG. Be aware the file will get larger, and JPG compression artifacts already baked into the photo won't disappear — PNG just stops further quality loss.
JPG (JPEG) offers small file sizes for photos using lossy compression, with no transparency support — it's the right format for photographs, email attachments, and anywhere file size matters more than pixel-perfect edges. PNG (Portable Network Graphics) offers lossless compression and full transparency support, at the cost of much larger files for photographic images, which makes it ideal for screenshots, logos, diagrams, and any image that needs a transparent background. This converter decodes your JPG and re-encodes it as PNG entirely inside your browser using the Canvas API — the file is never uploaded, so there's no size limit, no queue, and no privacy trade-off.
How to use the jpg to png converter

Frequently asked questions
Will converting JPG to PNG improve quality?
No — compression artifacts already in the JPG are permanent. Converting to PNG prevents any further loss in future edits, but it can't restore detail the original JPG compression discarded.
Is there a file size limit?
No hard limit — because conversion happens on your own device, there's no server cap. Very large images are bounded only by your browser's memory.
Are my JPG files uploaded?
No. The conversion uses your browser's built-in image engine (the Canvas API). Your image never leaves your computer, which you can verify by loading this page and then disconnecting from the internet — conversion still works.
Can I convert multiple files?
Yes — select or drop several files at once and each is converted and listed for download individually.
